Even the GT5 course designer is able to handle this simple task of auto generating the backgrounds and road textures.
We'll just have to agree to disagree on this. I don't think that's how the GT5 course maker works.
So it's been done before.
We'll just have to agree to disagree here I think as well.
Well I don't claim to know much about this stuff. If you say it can't be done, or that it's extremely hard, I'll have to take your word for it. Sounds like you've done more of the modeling than I have. As a software engineer, it doesn't seem like it would be that hard to designate polygons as either road surface, background / grass and background / sky. But if you say it's hard, I'll believe you. To me, the only really hard bit would be translating GPS numbers into the actual polygons. That bit might actually be very hard, especially when you consider that the road surface will be changing elevation and camber all the time. Having the background match up ... yeah, that'd be something. But still, I think it's certainly doable by someone. I bet we see this technology soon.
